I heard from someone that 235/60/15s were too low on the front so they went instead with 235/70/15.. is this something to take into consideration?? does the front sink in? any experience with this?

I looking to get some tires ...

I currently have 215/70/14's in the front and 255/60/15s in the rear.. It came in this set up when I bought the car.

 

A 235/70-15 is at least 28" diameter - pretty tall for a front tire. It might end up looking like a 4x4. If you're looking to switch to 15" wheels up front, pick a tire that's close in diameter to your 255/60-15 rears or it will look a little odd.
255/60's are about 27" diameter. A 215/70 is a pretty close match at about 26-7/8".

 

I have the BFG P255/60/R15 all around. I like the look, but understand everyone has their personal preference. I have not had any tire rubbing or interference in the front wheel wells. I have the adjustable airshocks in the back, so maybe they were adjusted by the prior owner to make the front look ok?

 

Both tire sizes in question will cause you no problems. The following URL will show you both tire sizes: http://www.miata.net/garage/tirecalc.html

 

sounds good !! will post pics soon.

 

I have 235/60/15s all the way around on my 72 and it looks good to me, would post a pic but I cant get a good shot in the garage.

 

just bought a pair of bf goodrich radial TA 235/60r15s for the front and 255/60r15s for the rear they are sitting in the basement, cant wait to get them on ...

im suprised to see that 255's alittle taller considering they are both for 15's and same height - 60s..
